EMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 42 26 1, dated April12, 1864.

To all whom it may concern:

Be it known that I, SAMUEL ALAND, of Rome, in county of Oneida and'Stateof New York,have invented anew and Improved Mode of Constructingsubsoil-Flows; and I do hereby declare that the following is a full andexact description thereof, reference being had to the accompanyingdrawings, and to the let ters of reference marked thereon.

The nature of my invention consists in providing a subsoil attachmentwherein the shoe is placed back from the plow a sufficient distanoe toadmit of its clearing itself in a superior manner; also, of adjustingthe standard both at the upper and lower ends, in order to obtain theproper pitch of the shoe, together with the brace and crossbar, which,as combined and arranged, produces a practical and Seperior improvement.

To enable others skilled in the artto make and use my invention, 1 willproceed to describe its construction.

A, Figure 1, is a perspective view of a plow, showing the subsoilattachment in the rear. The standard B is extended below the bottom ofthe plow, as when in use.

C, Fig. 2, is a longitudinal sectional view of the standard, notched.bar 0, and cross-bar D. The notched rod may be attached to the standardin any convenient manner that will admit of a free movement up and down.The other end is provided with notches or depressions of any suitableform that may be re-.

quired to secure it to a lug, G, cast on the mold-board or bolted to thelandside; or it may be made to hook over a bolt passing through the plowin any way that will render it adjustable. The standard B is madeeitherof wrought or cast iron, and in all cases should be made in such shapeand form as to throw the shoe back a sufficient distance from themold-board to allow it to clear itself readily in all kinds of soil. Itwill also be seen that the front and upper part of the standard must beprovided with teeth or notches to agree with the inside form of themortise in cross-bar D, said mortise being constructed with a V in thefront side to engage and fit the depressions in the standards, where itis easily and firmly secured by wedge E. The sides of the mortise shouldalso be rounded sufficient to allow the standard to rock back and forthto obtain the required pitch of shoe. One end of the cross-bar is madeto extend under the rear end of the plow-beam in the form of an angularbrace, F, which serves, when so constructed, the double purpose ofsecuring the beam to the handle of the plow, and also admits of itsbeing readily adjusted sidewise, and retained in any desired position.

It is evident that the rod 0 can be made in various ways and attached tothe standards and plow by different methods that will admit of the partsbeing adjusted to the different form and styles of plows without changing the nature of the invention.

I am aware that plows having subsoil attachments somewhat similar tothis have been made; also, that the rear end of a plow-beam has beenmade adjustable. I do not therefore claim, broadly speaking, asubsoil-plow having an adjustable beam; but

I claim- The combination of the mortised cross-bar D, standard B, braceO, and lug Gr, constructed and arranged to operate as and for thepurpose herein set forth.

SAMUEL ALAND.
